Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of SBUX price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: January 4, 2023
End date: July 26, 2024
a = 5.2887
b = -0.0005
s = 0.0534
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0005) – 1
= -16.39%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0534) – 1
= 23.82%

Top border of price channel:
Exp(Y866)
= Exp(a + b × X866 + 2 × s)
= Exp(a + b × 1,255 + 2 × s)
= Exp(5.2887 + -0.0005 × 1,255 + 2 × 0.0534)
= Exp(4.7801)
= $119.11
Bottom border of price channel:
Exp(Y866)
= Exp(a + b × X866 – 2 × s)
= Exp(a + b × 1,255 – 2 × s)
= Exp(5.2887 + -0.0005 × 1,255 – 2 × 0.0534)
= Exp(4.5665)
= $96.20
